Requested feature overview description.
Blips does not particularly work.
Why would it be useful?
So that false positives do not occur or could be switched off
What part(s) of the site page(s) are affected?
Blips page, my profile page
The search should be regular expression: /\busernam\b/gi ; instead, blips are found without regard to word boundaries:
